;: sl epers are secured, arerigidly anchored to the plastic supporting means.

A still further object is to provide an economical structure to accomplish the above features.

Gther objects and advantages will be apdescription. p

In the accompanying drawings forming a part of the specification and in which like J numerals are employed to designate like pa rts throughout the same,

Figure 1 is a plan'view of one sectionof my invention, showing the same previous to the embedding in the plastic support,

Figure 2 is an enlarged detail cross section taken on theline 22 of Figure 1, and

Figure 3 is an enlarged detail side elevation of Figure 2. r

In order to lay a wooden floor upon a hollow tile, concrete base or other base not penetrable to nails, it is necessary to first. position sleepers upon the base to which the floor boards are to be nailed. It is imperative that the sleepers be properly spaced and also I leveled with respect to each other. It has been found from experience that when the sleepers are fastened to blocks embedded in the concrete and plastic material placed thereunder, as is sometimes done, the dampness of the concrete first swells the sleepers and after they dry out there is a space left between the sleepers and the supporting blocks and base with the result that asqueeky springy floor will be present. I have therefor provided means whereby after the sleep- 7 i557 and 8.

ers have dried out the same may be tightened down upon the supporting blocks andbasc.

In the accompanying ilrawings wherein for the purpose of illustrationis shown a preferred embodiment of my invention, the nu nieralo designatesthe floor of a building which maybe of hollow tile, concrete or any series of parallel plastic strips as shown at The numerals 9 and 11 refer to angle iron other material. 'Upon this floor I first lay a leveling barswhich are leveledthrough the medium of screws 12. Suspended from the bars 9 andll are sleepers designated by the numerals 14, 16 and 17. vThese sleepersare preferably made of wood and have attached thereto at spaced intervals metal supporting blocks as shown at lS, 19 and 2 1. A screw .22 extends through each sleeper and into each block. The blocks are provided with w1ngs23and 24 which serve to carry tie rods as shown at 26 and 27 respectively. These tie rods form and anchor. in the plastic strips. The construction thus far described is laid upon the plastic strips and then forced ClOWllwardly into the plastic strips so that the same assumes the position shown in Figure 2; -The result of this construction is that after theiplastic material has been pointed 7 up about the embeddedportions and has setting up the next section of sleepers. As soon as the sleepers and supporting base have dried the screws 22' are tightened, thus bringing the'sleepers into intimate contact with their blocks and the base,thus producing a solid sleeper to which the floor boards may be nailed. r

As illustrated to advantage in Figure 2, the numeral 15 designates an opening provided in the sleeper it that may serve either as a ventilating medium or asa means for the passing therethrough of conduits or the like. h

' It will thus be seen that I have produced a lnn-( lened, the screws 31 are removelfl. andthe angle none 9 and ll are again employed in device which will accomplish all theobjects be taken as a preferred example of the same and that various changes relative to the material,-size, shape and arrangement of parts may be resortedto Without departing from the spirit of the invention or the scope of the subj oined claims,

.Having thus described my invention, 1 claim-: V e

1. In combination With a floor layingle l m vice comprising a pair of spaced parallel members having means for supporting said members at a predetermined height-abovea supporting surface, of sleepers secured to said parallel members, and suspended therebelow, and supporting members adjustably piarlried by said sleepers for the purpose specl- 2. In combination with a floor laying device comprising a pair of spaced parallel 2 members havingmeans for supporting said members at a predeterminedheightabove a supporting surface,ofsleepers secured to and below said parallel members, supporting members positioned beneath said sleepers, and means for adjusting said sleepers Wltll relation to said supporting members. "3. 'In combination with a floorlaying device comprising a'pairo'f spaced p'arallel supporting members having adjustable means for supportingsaid members ata point above a fixed surface, of a plurality ofsleepers carried by said parallel members, a plurality of supportin blocksthreadedlyseeured to the undersuri ace of said sleepers forthe purpose specified.

4. In combination With*a=fioorlayingdevice comprising a pair of spacedparallel supporting members having adjustable means for supporting said membersat' apoint above 40 *a'fixed surface, of-a plurality of sleepers carried by said parallel members, a plurality of supporting blocks threadedly secured to "the undersurface of saidsleepers and means carried by said blocks'for anchoring said blocks in aplasticcomposition.
